Abstract:
In the frame of the Seisbit® 3D RVSP project, a 3D drill-bit Reverse VSP was acquired in Sicily. The aim of the project is to obtain detailed information in the well area by using the working drill-bit source, and to demonstrate the reliability of the 3D seismic-while-drilling method in an onshore environment. A saw-toothed seismic layout was used to monitor, while-drilling, a vertical well run. Walkaway VSP and multi-offset CDP mapping were processed in the field to predict geological interfaces ahead of the bit and to obtain a reservoir 3D image.
